MeshCore firmware frame for cmd 0x03 is
`[cmd][txt_type][channel][timestamp_le32][text]`, not `[cmd][channel][text]`.
Missing txt_type + timestamp caused every channel broadcast to come
back with ERR_UNSUPPORTED, which broke the DM-via-channel path
entirely (nothing was reaching the radio). Bring the frame into
spec — verified against meshcore-dev/MeshCore docs/companion_protocol.md.

Meshcore direct unicast silently drops between our two Archy nodes
(firmware reports flood sends with resp_code=6 but nothing arrives).
Wrap DMs as channel-1 broadcasts with a [0xD1][dest_prefix(6)][inner]
header; receivers filter by prefix and dispatch the inner payload
through the existing typed/base64/chunk ladder. Shrink chunk body to
125B so the wrapper still fits the 160B LoRa budget. Auto-heal
routing: CMD_RESET_PATH (0x0D) any type-1 contact with path_len=0 on
refresh so floods take over. send_text now returns the firmware's
flood/direct mode flag for diagnostics.
Disable the 120s presence heartbeat broadcaster — its CBOR payload
was being re-echoed as plaintext by the shared repeater, spamming
every visible node with garbled "Archy-…: av�…fstatusfonline…"
messages on channel 0. mesh.broadcast-presence RPC stays registered
but no longer transmits. Re-enable only once presence moves off the
shared broadcast path.
Also: MeshState.cmd_tx behind RwLock so stop()→start() cycles don't
fail with "command channel already consumed"; MeshService.send_cmd
helper; drop_message_by_id for control envelopes that shouldn't
appear as Sent bubbles; self_advert_name reflected into MeshStatus
after set; path_len/flags parsed out of RESP_CONTACT.
Frontend: unified inbox merges mesh peers with federation nodes by
DID/pubkey/name; hide presence/read_receipt/edit/channel_invite/
contact_card from chat stream; publicChannel index → 1 to match the
new DM-via-channel routing.

Replace fragmented random key generation with a single 24-word BIP-39
mnemonic that deterministically derives all node keys: Ed25519 (DID),
secp256k1 (Nostr/Bitcoin), BIP-84 xprv (Bitcoin Core), and LND aezeed
entropy. New onboarding flow: seed generate → word verification → identity
naming. Restore path enabled via 24-word entry. Includes seed RPC handlers,
mock backend support, LND/Bitcoin Core wallet-from-seed integration, and
UI polish across settings and discover views.
